Two weeks ago, in what was the first official shot across the bow to Europe's long-standing "Schengen" customs union, we reported that the Italian province of Bolzano across from the Austrian border announced it is willing to "temporarily suspend Schengen" and "restore border controls" following a request by the German state of Bavaria. 

Today, none other than Europe's master state, Germany itself, is about to launch an ICBM at Schengen when, as BBC reports, "Germany is to reintroduce some form of controls on its border with Austria to cope with the influx of migrants, German and Austrian media report." While the BBC said that it is not clear what measures would be introduced, it is likely that a full return to the pre-Schengen era, with extensive customs checks of every border crosser is imminent. 

BBBC further reports that"more than 13,000 migrants arrived into Munich alone on Saturday. Germany's vice-chancellor said the country was "at the limit of its capabilities".
